Application filed January in the transverse spreading flue 16. The ends of the transverse inthe' lateral'flues 17, from the ends of fine 16 are continued Buffalo, in the county of Erie and State of which the air escapes into the chambers 18 New York, have invented certain new and and passes out by means of the outlet flues useful Improvements in Incubators, of 19. The heating fluid or hot air is brought which the following is a specification. in by the common trunk or main 20, having This invention relates to incubators, and i the vertical connecting flues 21 for carrying the heating fluid from the main to the compartrnents situated above each other. .The inlet flue 15 for each compartment or heating box is connected with a vertical flue 21,

consists in the apparatus hereinafter described and claimed.

In the drawings :Figure 1 is a front elevation oi a device embodyingthis invention; Fig. 2 is a horizontal section on the line 2-2 of Fig. lg'Fig. 3 is a vertical section on the line 3-3 of Fig. 1; Fig. 4 is a front elevation of a modified form of the invention; Fig. 5 is a horizontal section on either of the lines 5*?) of Fig. 4e; and Fig. the line 6-6 of Fig. 4. Figs. 7 and 8 are vertical sections of a supplementary jacket and part of a lateral air conduit having modified forms of damper devices.

The main purpose of this invention is to provide a large incubator device capable of hatching large numbers of eggs, which is divided into compartments, each capable of control independently of the others, but all fed with heat preferably from a common source of supply, and provided with circulating means that is common to all comartments but independent as to each.

In the device illustrated in Figs. 1, 2 and 3, the several compartments are fed with heated air for producing the heating of the egg chamber, and the air is exhausted or led away by a separate outlet duct for each compartment. in the form of device shown in ig. 1, there are four compartments 1, 2, 3 and 4, each having its own door 5, 6, 7 or 8. Each compartment is divided into two portions by a horizontal porous diaphragm 9, separating the upper or heating chamber 10 from the lower or egg chamber 11. The egg chamber 11 contains one or more egg trays 12 supported therein at a suitable height from the bottom of the compartment, and in the lower part of each compartment, underneath the egg tray or trays, is one or more air outlets 13. The heating chamber 10 is provided with a heating box 14, having means of circulating a heating fluid therein, which fluid in the present case is hotir This air is brought into the box 14 throdgh the induction or inlet flue 15, which divides tends into the said vertical flue, and is provided with automatic means for cutting off the heating fluid from the compartment comprising a suitable valve, such as the valve 22 hinged in proximity to the beveled end 23. of the inlet fine. The end of the flue is. so beveled as to have a downwardly-directed opening, and the valve is so hung that the air rising in the flue will be defiected. from the face of the valveinto the end of the flue. Each valve 22 is suitably connected to a balanced lever or bar 24 convenicntly placed upon the top of the compartment to which it relates, suitably pivoted on a support 25, and having a c0unterbalance weight 26. The lever or bar 24 is connected to a rod 27, which extends into the compartment, and is adapted to be op erated by a suitable thermostatic device 28 in the egg chamber 11. By this means, as the temperature in the egg chamber rises. the valve will move toward-the closed position, cutting off to greater or less degree, or entirely, the inlet of heating fluid through the inlet flue l5.

Theoutlet fines 19 are connected with an outlet main 29 conveniently by vertical pipes 30 to which the said outlet fines connect directly. In the form of device shown in Figs. 1-3, there are two outlet fines 19 for each inlet fine 15 for the purpose of causing an even distribution of the heated air through;

of the cross-sections of the outlet fines equal the area of the cross-section of the inlet fines.

The inlet main 20 is connected with a proper source of heat, which may be an ordinnry hot air furnace, and the outlet main 29 carried to the outer air.

A supplementary jacket 31 surrounds the vertical flue 21 adjacent to each heating and in one example of this invention ex-' out the heating box 14. The co -ibined areas are chamber 10. This jacket 31 is closed at top .32, and has a ventilating conduit or fresh air duct leading into the heating chamber 10 beneath the heating box 14.

The line 21 carr in heated air wih b radi-- at-ion, heat in the space between the jacket 31 and said flue 21, and the air thus heated will rise and pass through the duct into the heating chamber .10, downward through the porous diaphragm 9, through the egg chamber 13. and out through the air outlets l3. ihusa constant movement of air through the egg chamber 11 is provided for.

It will be noted that the volume of air that may pass into the heating box 145 from. the main 20,,and thence through the outlet pipes and main 29, may be very considerable, and consequently the air passing through the heating box i l in great volume will not need to be highly heated in order to eoniheat to the egg chain-be; ll. ()nly such a degree of heat is necessary the radiation there;

municate suflicient in the box 1 as will by from, and by the inlet of heated air through the fresh air duct keep the temperature of the egg chamber at the required point, namely; at about 103 F.

continuous current 01 sulll iently heated air is passing through the box-lei, and the inlet of air to each such box is co itrollcd by the thermostatic arrangement and valve belonging to that compartment. When the temperature in a compartment rises too high,,the valve 22 is closed and the inlet of heat is cut oil", but. the chilling of that compartment by too rapid ingress of cold air is not possible because, when the valve is closed, the air remains "substantlally immovable ill. the box 14-, and said box will cool down gradually without causthe egg chamber through theduct [as soon as the chamber cools down to a proper degree the valve 22 will open and the heating of the box lat will-be resumed. These operation as to any one compartment do not a any other compartment.

In the form oit igs. 4t, 5

device shown in B and 6, a hot water or steam .circulation system substituted. for the box 14, although in all the cases a. fluid is employed for pro ducing the heating, and said fluid is conto a radiating conduit, consisting of the pipes 35 in the heating chamber 10 of each incubator compartment; These pipes are attached at their outlet ends by connections 39 with return or outlet pipes or mains 40.- A supplementary jacket 4-1 is provided around the connections 36 and 39, which are 7 By this device a independently mg any too great indrat't of cold air into preferably vertical, and this jacket closed at its top 42, except as hereinafter described, and is provided with the lateral air conduit 43 extending into the heating chamber 10 above the diaphragm 9, so that air may enter the open bottom. of the jacket ell, and, be-

ing heated by the pipes 36, 38 and 39, is

is closed, air passes into the heating chamopen, but when said damper ber l0 through the conduit 43. The damper 4-4: is connected to a lever or bar 24 of the same construction and 1s operated in exactly the same manner as has been just described.

In Figs. 7 and 8 are shown valve devices that are equivalents of those shown in other figures.
